Standard Common Name
Barred Sand Burrower, Sand-diver, Striped Sand-diver.
The Tommyfish is an elongate fish that has a pointed snout and upwardly directed eyes. It can be recognised by its colouration. There is a series of dark blotches on the back that give the fish a banded pattern. It is pale below.
This species was described in 1904 by former Australian Museum Fish Curator, Edgar Ravenswood Waite. The syntypes are stored in the Australian Museum Fish Collection (AMS I.5854, I.5855, I.5856 and I.5858).
The Tommyfish looks similar to the Elegant Sandburrower, Limnichthys nitidus. They can be separated by the number of soft dorsal fin rays (49-55 in L. fasciatus vs. 44-51) and some of the dorsal saddles reaching a distinct lateral band versus no saddles reaching a lateral band.
The Tommyfish grows to 6 cm in length.
The species occurs in shallow tropical and temperate marine waters of the Western Pacific, including Australia, New Zealand, the Kermadec Islands and possibly Japan.
In Australia it is known from southern Western Australia to north-western Western Australia and the northern Great Barrier Reef, Queensland, south to the southern coast of New South Wales and Lord Howe Island.
